FRAME STRUCTURE FOR SELF-BINDING HARVESTERS.

SPECIFICATION forming part of Letters Patent No. 512,001, dated January 2, 1894.

Application filed March 31, 1892. Serial No. 427,297. (No model.)

T 00% whom it may concern.-

Be it known that I, WIL IAM BUTTERFIELD, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Frame Structures of Self -Binding Harvesters, of which the following is a full description, reference being had to the accompanying drawings.

Figure 1 is a front elevation of the frame work forming the subject matter of my invention; Fig. 2 a rear elevation of the same, the binder table being removed; Fig. 3 aperspective view of the sills of the main frame, and Fig. 4 a stubble-side elevation.

One-of the objects of my invention is to dispense with what is known as the rear A- frame of a harvesting machine. This I accomplish by elevating the rear portion of the main wheel frame so that the elevator may be connected directly thereto, and also, that the binding attachment, at the rear end, may

, be connected directly to the parts of the said main wheel frame.

A is the finger bar, a the guards and sickle, and a the platform conveyer.

A is the front main sill, suitably saddled to the finger bar preferably a considerable distance above the latter. The elevation of the front sill enables me to reduce the vertical dimensions of the front A-frame supports.

B is a forwardly extending arm which serves as a point of attachment for the draft tongue. It is adapted at b, to form the saddle between the finger bar and the front sill A, from which point it is extended rearwardly and upwardly and formed into the lug b, to which the grain-side side-bar of the main wheel is bolted.

O is an arm secured to the stubble end of the front sill A, adapted to receive, at c, the crank shaft, and is extended rearwardly and upwardly, terminating in the lug c, which is bolted to the stubble-side side-bar of the main wheel frame.

D is the rear end-piece of the wheel frame, having a socket (l for the seat spring, and an arm cl adapted to support a journal bearing for the crank shaft.

d is a lug, having formed therein a sleeve which receives the journal bearing for the cross-shaft D.

d is a downwardly extended bracket, having the sleeve-like supportfor the journal bearing of the grain-end of the shaft D.

O and O are the side bars of the main wheel frame, the former secured to the lug b by B, and to a projection on the casting D that is a part of d The bar 0 is secured at its forward end to the lug c, and to the side of the arm 61.

E is the rear platform sill, and E a part that may be considered an extension thereof deflected upward to reach the rear end piece D and secured thereto, being bolted to the lugs 01 E forms the grain-end sill of the platform. The main wheel is shown in place, but as the axle, and the means for supporting the frame on it, forms no part of my present invention, I have omitted it.

Upon the sill A is footed the frame-like bracket F for sustaining the front A-frame, the forward end of the self-binding attachment, and take theforward end of the tie-rods that connect it to the rear part of the frame work. An ear, f, is extended upwardly and stubbleward, and to it is bolted the front A- frame plate, which I make of thin metal. To give proper rigidity, the bolt also passes through the wooden canvas slide shown in dotted lines. At the base of the ear f, an eye is provided, and through this passes a tie-rodf, thence to the rear of the machine where it is hooked into an eye f in the rear end-piece D;-

g and g are arms extended downward and grainward from the part, g, of the binder table, and having eyes through which the tierod f passes. This means forsupporting the upper end of the binder table serves an important purpose. In all machines known to me said binder table is secured to the elevator frames at its upper end, and the result is that straggling straws gather into space between delivery end of the elevating aprons and the binder table, and hang to whatever serves to connect the table to said elevator frame.

Reference to Figs. 1 and 4 will show thatl have a clear space between the binder table and parts of elevator and elevator frame, and nothing upon which the straws may gather.

to the shoe H. Journaled near its foot is the shaft h of the lowermost elevator drum, and secured thereto is the sprocket wheel h. At the upper end of the elevator is the uppermost elevator drum, having a shaft 71 and keyed thereto the sprocket wheel h It is a sprocket wheel supported upon the plate 71*, the latter being bolted to the front elevator wall-piece, forming a journal bearing for the shaft h and also having a lug to which the grain cover support h is bolted.

1 As one piece with the sprocket wheel If is the bevel gear W, from which, by means of a horizontal shaft shown in dotted lines, and a similar gear, motion is imparted to the reel, not shown.

H is a sprocket wheel on the crank shaft, H a crank formed on the same shaft, and H the pitman; the latter connected at H- to the knife head, which is guided by the cap H H is a sprocket wheel that serves as a tightener for the chain H by means of which chain all of the sprocket wheels so far mentioned are driven. The position of the crank shaft will be best understood by referring to Fig. 4, where it is seen journaled in the bearings held in the supports before mentioned.

I, is the binder driving sprocket wheel, lo

cated immediately in rear of the pitman crank.

Upon the axle of the main wheel is a large sprocket wheel J, and upon the shaft D is the small sprocket wheel J, suitably clutched thereto. Upon the same shaft is the bevel gear J and upon the crank shaft apinion J From the crank shaft, through the sprocket wheels I and H, the rotary parts of the machine are driven.

The main binder frame K is footed upon flat bars lo, 70, 70, which, at their stubble ends are bolted to the bar K, preferably made of gas pipe in order to have stiifness and strength. This bar rests above and against the antifriction roller f and is held there by the keeper 10 which takes the bolt passing through the stud upon which the anti-friction roller turns, and is locked to the frame F by means of a key k passing through a suitable lug.

At the rear end of the bar K is secured a guide piece It, having an eye to receive the tie-rod f and to slide thereon. This guide with the anti-friction roller f preserves parallelism of the binder frame relative to the harvester frame.

Crossing the flat bars k, 7t at the stubbleside of the base of the binder frame, is secured another large bar K also preferably of gas pipe of the same dimensions as K.

Secured to the base portion of the front frame is the brace L, having at its upper end an anti-friction roller Z, suitably journaled therein. Over this the pipe K rolls as the binding attachment is moved fore and aft to adapt the same for central binding of the grain.

Upreaching from the pipes K and K are the standards g g g and 9 to which is secured the binder table G. The shaft h of the lower elevator drum extends to the rear of the machine, and to it is secured the pinion m.

Secured to the rear journal of the conveying canvas drum is the pinion m.

Intermediate between the two pinions last referred to and meshing therewith, is the pinion m. The latter conveys movement from the pinion 'm, to that m.

It will be readily seen that I locate all parts for giving motion to the elevating and conveying devices in front of the line, of travel of the swath, and beneath it, so that my machine, having, as it does, an open end elevator, need not be wide from front to rear. In order, however, to give the elevator the necessary length to support the grain, I provide the elevator extension board N. Upreaching from the frame portion E are the two spring arms 11 and 'n'. In order to render them sufficiently elastic and also to escape the line of travel of the heads of the gra n, I bow them backwardly, as shown in Fig. 4. Their upper ends are secured to the bar 0, which forms a guide for the elevating canvas as well as journal bearings for its drum. This elastic support for the canvas guide and journal bearings is important as it allows the rear portion of the elevator to expand and permit the passage of masses of gram that oftentimes move along the rear of the conveying canyas.

To the lower portion of the elastic elevator supports 72 and 'n' the board N-is secured. The front journal bearings of the uppermost elevating canvases are loosely held in supports so that the rear part of the said elevating canvas may rise and fall to the extent required without cramping and producing friction.

P is the bundle carrier support, thrust through openings 19 and c of the castings B and 0. Providing these castings with openings, as I do, permits the attachment and detachment of the bundle carrier quickly. It is a provision whereby a bundle carrier, if not purchased with the machine, may be readily attached at any subsequent time.

In many respects the two sills A and A too may be considered as a single front sill bent higher at the stubble end, if desired, instead of being held up by means of saddles.

The self-binder is adapted to be moved back and forth by means of the lever Q, pivoted at q, and having the upreaching arm q, to which the rod g is connected, the latter hooked into the rearmost bar is.

In order to accomplish as much adjustment as possible by means of the lever Q, two eyes are provided into which the rod (1 maybe secured.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The main wheel frame elevated at its rear end so as to directly support the rearmost elevator frame, the platform having the upwardly directed rear sill connected thereto, and having the sill A-A, to which the front and lower end of the wheel frameis connected, all combined substantially as described.

2. In a harvesting machine, the front sill AA', the main wheel frame secured to the stubble end of the same and directed u pwardly and rearwardly, the rear sill EE' directed stubbleward and upward at the stubble end, and also suitably connected to the main wheel frame and the sill E connecting the front and rear sills at the grainward end, substantially as described.

3. In a harvesting machine, the diagonal main wheel frame, having at its upper end the rear cross frame piece D, the latter having downhangers which form supports for the journal bearings of the shaft that receives motion from the main axle and also lugs to receive the upwardly deflected part E of the rear sill, substantially as described.

4. In a harvesting machine, the diagonal main wheel frame, having at its upper end the rear cross frame piece D, the latter having downhangers which form supports for the I journal bearings of the shaft that receives motion from the main axle and the upreaching shaft support 0 at its front end, substantially as described.

5. In a harvesting machine, the front sill, the main wheel frame secured at its front end thereto and having the diagonally placed sills C and O secured to the rear end piece, the latter provided with a recess for the seat spring, brackets for the support of the various journal bearings, and lugs for securement to the upwardly directed bar E of the rear sill, all combined substantially as described.

6. 'The combination of the main wheel frame-bars, the front sill A, the bracket pieces B and (J, the latter provided with places for securement of the bundle carrier supporting bar, substantially as described.

7. The combination of the diagonally placed. side-bars of the main wheel frame, suitably connected together at the rear end, the front sill A, to which they are secured, the frame Fsecured to the said front sill and connected by means of tie rods to the elevated rear end of said main wheel frame, thus formingasupport for the elevating devices and self-binding attachment, substantially as described.

8. In a harvesting machine, the combination of the main wheel frame, so high at its rear end as to permit the elevating devices to be secured directly thereto, the bracket F footed and secured to the front sill and tied to the rear end of said main wheel frame, the front elevator frame footed upon the finger bar and secured to the bracket F, thus forming a brace for the latter, substantially as described.
